It's not at all unusual to mix sizes, 1080, 720 etc. If you can define the size of your project sequence, choose to work in 720 (in this instance) and scale your 1080 file to 68% of the original size. The finished project should render well unless you also are mixing fps i.e. 24fps and 30fps.
Excellent. Thank you for the simple and concise answer!
If you're using Adobe Premiere Pro, you may also use the "scale to frame size" option…
If you have After Effects, you can just scale it down to 720p. That's actually a good plan if you've got intentions to have slow motion footage in your piece. Most rigs will have faster frame rates in a smaller format. HD cameras usually go with 1080 30p and 720 60p. You can shoot all your main footage in 1080 and your hard action intended for slo-mo in 720. When you're done, scale it all down to 720p so you don't lose image quality trying to scale up to 1080.
